I'm not sure if this is something which crept into a recent release of Dovecot, or a problem with T'bird, or something else entirely. I had suspected corrupt messages the first time or two, and was once able to copy such a message into my own "Maildir/cur" directory and have it fail for me. Since then I've not been able to replicate this feat. I also thought that it might have been the Dovecot indices becoming corrupt but today I tried purging them for an affected user, and the problem still showed up. In addition, for the first time today that user reported a message which originally (as of 6 Nov. 2008) worked fine but today demonstrates the issue.
If there's a problem with indexes, Dovecot most likely would have logged an error message. Do you see any errors logged?
If anyone has seen anything like this or has suggestions to try, please let me know. If necessary I can go to full debug-logging with Dovecot but I'd prefer to avoid that if possible :)
Knowing what Thunderbird and Dovecot talk to each others would be pretty much the only way to know what's going on. http://wiki.dovecot.org/Debugging/Rawlog would help.
